Rutherford police and the Bergen County Prosecutor's Office Special Victim's Unit arrested Jose M. Olivares, 25, after a joint investigation.

The arrest came a day after Rutherford police received the initial report from a chaperone.

The 16-year-old was staying in a room at a Rutherford hotel with two other juveniles. The group was on a trip from Syracuse on Sept. 15 when the incident allegedly occurred. Olivares allegedly assaulted the boy inside the room.

The victim reported the assault to a chaperone shortly after the incident occurred, the press release reads.

The chaperone contacted the Rutherford Police Department.

Olivares fled the hotel, leaving police and the prosecutor's office searching for the accused until late into the next day, Sept. 16. Olivares was eventually arrested at his Jersey City home on Clendenny Avenue.

Olivares faces two criminal charges: second-degree sexual assault and third-degree endangerment of the welfare of a child.

Superior Court Judge James G. Guida set bail at $100,000 with no 10-percent option.
